Bell 525 Relentless vs Cessna 208b Grand Caravan Ex vs Daher Tbm 960 vs Gulfstream G700
The Bell 525 Relentless is a fly-by-wire, twin‑engine helicopter focused on vertical access rather than long cruise efficiency; it typically serves short to medium missions (generally a few hundred nautical miles, depending on reserves and payload) and carries around 16 passengers in a high-density configuration. The Cessna 208B Grand Caravan EX is a single‑engine utility turboprop in the “workhorse” category; it offers short to moderate range (often on the order of ~900–1,200 nm in typical planning) and commonly seats about 9–14 passengers depending on layout. The Daher TBM 960 is a high‑performance single‑engine turboprop aimed at fast owner‑operation and point‑to‑point travel; it is long‑range for its class (roughly ~1,400–1,700 nm) but carries fewer people, typically 4–6 passengers in a premium cabin. The Gulfstream G700 is an ultra‑long‑range large‑cabin business jet; it leads on range (about ~7,500 nm class) and carries the most in comfort, typically 12–19 passengers depending on configuration.
